Answer 1

here is a basic guide of how this can be done...

// Set the next delivery date
var NextDelivery = null;

function CalcTimeOut(){
   var cutOffTime = new Date();
   var currentTime = new Date();
   var difference = null;

   if(cutOffTime.getHours() < 12) {
      // If we are before 12 we can deliver today
       cutOffTime.setHours(12,0,0,0);
      NextDelivery = new Date();
   } else {
      // Set new cutoff time
      cutOffTime.setHours(36,0,0,0);
      // If we are after 12 we can only deliver tomorrow.
      var currentDate = new Date();
      currentDate.setDate(currentDate.getDate() + 1);
      currentDate.setHours(0,0,0,0);
      NextDelivery = currentDate;
   }
   var difference = (cutOffTime.getTime() - currentTime.getTime());
   // Recalculate if we need to...
   setTimeout(function(){
      CalcTimeOut();
   }, difference);
}

// Call from where ever you need to.
CalcTimeOut();
